SPINDLE AND BOLSTER FOR SPINNING AND TWISTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 322,654, dated July 21, 1885.

Application led August 5, 1884. (No model.)

To aZZ whom it may concern.-

Beit known that I, JAMES J. SUMNER, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Spindles and Bolsters for Spinning and Twisting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The object of my invention is to produce a spindle and bolster in which the lubricant shall maintain a constant circulation, due to. the rotation of the spindle, whereby great economy and cleanliness in the use of the lubricant are attained.

To the above purpose my invention consists in the peculiar and novel construction and ar'- rangement of the spindle and bolster, as hereinafter described and claimed.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which` Figure lis a vertical section of my improvement, the spindle being shown in elevation. Fig. 2 is a similar view ofthe bolster and the sleeve and ring.

In the said drawings, A designates the stem of the spindle, which carries the usual whirl,

a. Above the whirl is formed an annular socket, a', the rim of which is concentric with the stem of the spindle.

B designates the bolster, which is formed at its base with an enlarged internal socket, b, upwardly from which extends the bore of the bolster.

b designates an annular projection, which is formed upon the outside of the bolster, and in the upper side of which is .formed the annular channel b2. A duct, b3, extends ololiquely downward from the bottom of the channel b2 and opens into the bore of the bolster. At the upper end the bolster is formed with an annular series of holes, b, and its upper The sides of the bore of this sleeve are formed with a worm, c, and throughone side of the sleeve is formed an oblique duct, c', corresponding with the duet b3 of the bolster B.

D designates a ring, which is set into the upper end of the bolster B, and which closely hugs the stem A, so as to revolve with it. The outer side of this ring is beveled inwardly at its upper portion, as shown, so as to close the joint between the ring and the bolster. ring lies just above the holes b4. The ring D is rst dropped into the bolster, and then the sleeve C is forced tightly into the bore of the bolster. The stem A is then inserted upward through the bore of the bolster, and is forced Well into the ring D. Oil is now run into the channel b2,- and liows through the ducts b3 and c into the bore of the sleeve. As the stem revolves the oil will be drawn upward along the The Worm Vc until it reaches the series of holes b,

at which point its upward passage will cease,

because the joint between the ring D and' c into the worm, upward out of the holes, and

thence downward into the channel b2 again, and so on repeatedly. Thus it will be seen that the spindle is virtually self-oiling, and that it automatically causes a constant circulation of the lubricant, so that the utmost economy in the use of lubricant is attained, while waste and dirt are avoided.

I do not wish to be understood as confining myself exclusively to the precise details of constructionV above described, because such details are susceptible of various modifications. For instance, the upper end of the bolster may be formed separately from the body thereof, as is indicated by the lines X Xin the drawings, and in this event this detachable portion would be forced around the upper end of the sleeve C after the ring D had been placed within said upper' portion. Other similar modifications may be made without departing from the spirit of my invention.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- 1. The oombination,wth the spindle proper, the sleevehaving the worm c and duet c. and of the bolster, the sleeve, and the ring, conthe ring D, substantially as and for the purstruoted and arranged substantially as and for poses set forth.
